Abstract A numerical method of liquid pouring from a beverage can was proposed in the present paper, and a numerical model of the effects of dew condensation on the flow from the can was also developed. An experimental observation showed that the liquid flowed over the can lid and was once obstructed by the rim of the lid. Then, it flowed over the rim and fell off, forming a V-shaped surface. The numerical result agreed with the experimental result. Effects of condensation formed on a can surface were also simulated. In the simulation, the effect of condensation was considered by adjusting a contact angle, defined as an “effective” contact angle. The trajectory of the falling liquid came close to the can body for higher wettability by condensation. With more condensation, the liquid pouring from a can trickled down along the can body. The computation reproduces these experimental observations.

饮料罐倒液的实验与数值研究

摘要 本文提出了饮料罐中液体倒出的数值方法，并建立了露水凝结对罐内流动影响的数值模型。实验观察表明，液体流过罐盖，一度被罐盖边缘挡住。然后，它流过边缘并脱落，形成一个V形表面。数值结果与实验结果一致。还模拟了罐表面上形成的冷凝的影响。在模拟中，通过调整接触角来考虑冷凝的影响，接触角定义为“有效”接触角。下落液体的轨迹靠近罐身，以通过冷凝获得更高的润湿性。随着更多的冷凝，从罐中倒出的液体沿着罐身滴落。
